  • OBD

    serch.it?q=OBD

    OBD may refer to: On-board diagnostics, an electronics self diagnostic system, typically used in automotive applications Optimal biological dose, the quantity of a radiological or pharmacological treatment that will produce the desired effect with acceptable toxicity

  • OBDuino

    serch.it?q=OBDuino

    OBDuino is an open source trip computer design based on the Arduino platform. An OBDuino may be assembled and customised by an electronics hobbyist; it displays information such as instantaneous fuel economy (e.g. miles per gallon, L/100 km or kilometres per litre), engine tuning parameters etc. on an LCD. OBDuino utilises the On-Board Diagnostics interface found in most modern cars.

  • OBD-II PIDs

    serch.it?q=OBD-II-PIDs

    OBD-II PIDs (On-board diagnostics Parameter IDs) are codes used to request data from a vehicle, used as a diagnostic tool. SAE standard J1979 defines many OBD-II PIDs. All on-road vehicles and trucks sold in North America are required to support a subset of these codes, primarily for state mandated emissions inspections. Manufacturers also define additional PIDs specific to their vehicles. Though not mandated, many motorcycles also support OBD-II PIDs. In 1996, light duty vehicles (less than ) were the first to be mandated followed by medium duty vehicles (between ) in 2005. They are both required to be accessed through a standardized data link connector defined by SAE J1962. Heavy duty vehicles (greater than ) made after 2010, for sale in the US are allowed to support OBD-II diagnostics through SAE standard J1939-73 (a round diagnostic connector) according to CARB in title 13 CCR 1971.1. Some heavy duty trucks in North America use the SAE J1962 OBD-II diagnostic connector that is common with passenger cars, notably Mack and Volvo Trucks, however they use 29 bit CAN identifiers (unlike 11 bit headers used by passenger cars).
